HEAC

1. Product Overview
   HEAC (Hydrogen Embrittlement Armor Coating) is a breakthrough bio-based polymer composite barrier developed by U3H₂Trans Solution. Applied to cost-effective carbon steel (e.g., X70/X80), HEAC forms an ultra-dense, active micro-barrier that fundamentally suppresses hydrogen permeation and embrittlement under high-pressure pure hydrogen conditions—delivering safety performance far exceeding stainless steel at 60–70% lower total cost.

2. Core Technology

• “Brick-and-Mortar” Physical Barrier: A highly ordered layered nanostructure elongates hydrogen diffusion paths by >15×.
• “Molecular Lock” Chemical Trapping: Leveraging free-volume theory, the coating compresses polymer interstitial voids and actively immobilizes hydrogen atoms via polar functional groups, thereby suppressing permeation at its source.

4. Core Value Proposition

• Unmatched Safety: H₂ permeability 50%+ below GB/T 42610-2023; weld-zone embrittlement risk reduced by 92% (via proprietary H₂DGR™ process).
• Exceptional Economics: 60–70% TCO reduction; saves 42 tons of specialty steel per km of pipeline.
• Field-Ready: Supports in-situ recoating under pressure (≤15 MPa); fully compatible with standard line pipe steels.
• Sustainable: Bio-based, near-zero VOC, >90% annual biodegradability.

5. Applications

• Long-Distance Pipelines: Deployed in PetroChina’s 25-km pure H₂ pipeline (10 MPa), operating reliably for 2+ years.
• Onboard Storage: Enables 70MPa Type III tanks at 50% lower cost vs. Type IV.
• Refueling Stations: Used on storage vessels, high-pressure lines, and sensor diaphragms—cutting system costs by 50%.
• Industrial & Marine: Recycled hydrogen networks, offshore/shipborne fuel systems (4× longer maintenance intervals).
